Claims.

My invention relates to building construction and its object is to improve and cheapen the construction of concrete buildings and the product thereof.

I accomplish this object as illustrated in the 2 accompanying drawings in which:

Figure 1 is a sectional view-drawn to a relalively enlarged scale-of a portion of a wall of a building embodying my improvements, taken on or about line I--I-I-l of Figure 2, with the forms in place.

Figure 2 is a plan View showing a horizontal section taken through the empty forms.

Figure 3 is a perspective view, partly in section, showing a wall under construction, with the l Referring now to the reference characters upon the drawings:

The numeral 2 denotes a wall footing. Parallel and adjacent to the inner edge of the footing 2, is secured an angle-iron 3, with one portion extending in a vertical plane. Numeral 4, indicates thin metal tubular uprights, rectangular in crosssection, closed at their inner faces and open at their outer faces. These uprights are secured at their lower ends, at intervals, to the upright anges of the angle-iron 3,-see Figure 2. Each of these uprights consists of two members Z- shaped in cross-section, having outwardly ex-V tending iianges 4a, at their outer edges, and inwardly extending flanges 4b, at their inner edges,see Figure 3.

The inner flanges 4b, are again turned inward at right-angles, to form the ilanges 4c.

The two parts forming each of the uprights 4, are secured together bymeans of the flanges 4c. Numeral 5, denotes a wooden nailing strip clamped between the flanges 4c, having its inner surface flush with the inner edges of said flanges and extending into the hollow formed by the spaced walls of the uprights 4,-said latter portion being dove-tailed in cross-section. The

flanges 4c, and the nailing strip 5, are cutaway at the lower end ofthe uprights 4, to accommodatethe angle-iron 3, as shown in Figure 6.y

Numeral 6, indicates strips of a boardingmaterial, which may be a Celotex insulating sheath@ ing or the like, secured to and extending between the flanges .4a, of adjacent uprights 4, their edges registering with the inner edgesof said flanges, leaving the outer faces of the uprights 4,

unobstructed. v

Numeral 3a, denotes an angl'eeiron extending along the upper edges of the boarding material 6, serving as an aligning andv stienlng member. Numeral 6a, are spacing. lugs -of bent' sheet metal secured to the boarding 6, 'and' extending outwardly as required, toy determine'the thickness of the Vwall Vto be feast. Itwill, however, be understood thatwhile a relatively small number of the spacing lugs lia,V are shown in the several views of the drawin'gs,- -theY number employed may be increased asV required, to insure proper spacing `of the trays-hereafter more particularly described. f v ,f Numeral 1a', denotes reinforcingrods 'passing vertically through the .interior of each of Ythe uprights 4, :and arersupported by brackets l, extending from the sides ofthe uprights;

Numeral r8, vdenotesmetal strips-threaded at their inner ends upon the reinforcing. rods la, and at their outer ends are ,provided with apertures,-for purposeshereafter described.

Numeral 9, denotes hollow trays, and4 IIL-'see Figure 4, indicates sheets of coarse paper,` which are thoroughly saturated withy water, and placed in the bottom of the trays 9. Numeral I I denotes a layer of moist plastic clay covering the surface of the outer sheet of paper Ill.

Numeral l2, denotes a surface of aggregate or surfacing material, removably i'lxed in the plastic clay Il.

Numeral lr3denotes reinforcing rods extending upwardly from the footing 2,-then turning and extending horizontally through the space to be occupied by the wallV l. Numeral 4 indicates thev floor beams.

The web closing the inner surfaces of the uprights 4 is'cut away at the top, at 4d, as indicated over as indicated at 9a.

In constructing a wa11,-the trays partly lled as above described are placed end to end with their open face inward in position to form the outer wall of the form or mold, their edges engaging against the outer ends of the lugs 6a, to position them relative to the surface of the boarding 6, and the edges of the upper trays resting upon those of the lower trays. The strips 8 extend between and beyond the edges of the superimposed trays as shown in Figure 1. A strut I5, having engaging rods Ia, extending from its ends is placed between two vertically disposed strips 8 with its rods l5a, engaging in the apertures in the outer ends of said strips, and a channel iron I6, is then placed between the strut I5 and the trays 9. A bolt I'l at the center of the strut I5, is then screwed up against the channel iron I6, forcing the same inward and pressing the tray firmly into position.

When the outer wall of the form or mold is thus formed the concrete is poured in the space between the trays and the boarding 6, and ows into the tray against the surfacing material I2 therein, and into the uprights 4, and around the ends of the floor beams I4. When the concrete has set the trays are removed, the wall has its outer surface marked by grooves 9a, formed by the edges of the trays, giving the appearance of cut stone,-see Figure 5. The concrete will bind the surfacing material firmly to itself and the clay can be washed off leaving the surfacing material exposed to view. The concrete in the uprights 4, forms supporting studs integral with the walls and the ends of the joists, or floor beams and are firmly embedded in the concrete wall construction. The boards for the wall of the enclosure may be nailed to the strips as indicated at I8, in Figure 3.

What I claim is:

1. In an apparatus of the kind described, a plurality of vertical tubular uprights, closed at their inner faces and open at their outer faces; means secured to the lower ends of the uprights adapted for the attachment of the uprights to a wall footing; sheathing secured to the uprights, closing the space between the uprights; binding strips, adapted to be secured at their inner ends to vertical reinforcing rods supported by the uprights, a plurality of wall surface molding sections, said binding strips extending outwardly between and supporting said wall surface molding sections, supported by the binding strips; and clamping means, secured to the outer projecting ends of the binding strips, adapted to clamp the wall surface molding sections in position.

2. In an apparatus of the kind described, a plurality of vertical tubular uprights, closed at their inner faces and open at their outer faces; means secured to the lower ends of the uprights, adapted for attaching the uprights to a wall footing; sheathing secured to the uprights, closing the space between said uprights; outwardly extending spacing members carried by the sheathing, a plurality of wall surface molding sections aligned in spaced relation to said sheathing by the spacing members; binding strips, adapted to be secured at their inner ends to vertical reinforcing rods supported within the tubular uprights, said binding strips extending outwardly between and supporting the wall surface molding sections, and clamping means, secured to the outer projecting ends of the binding strips, adapted to clamp the wall surface molding sections in position against the spacing members.

3. In an apparatus of the kind described, vertical spaced tubular uprights adapted to be secured by supporting means upon a wall footing; a sheathing secured to the uprights, closing the space between the uprights; a plurality of wall surface molding sections, comprising hollow trays adapted to receive and support a plastic clay and aggregate coating for a concrete Wall; means for maintaining said wall surface molding sections in fixed spaced relation to said sheathing; and adjustable clamping means, clamping said wall surface molding sections against the means for maintaining said wall surface molding sections in xed spaced relation to the sheathing, to receive a concrete wall mixture.

4.
